A student wants to measure the temperature change of water after adding a 10 cm block of iron to container 1 and a 10 cm3 block of lead to container 2. Both
blocks were heated to 40°C before being added to the water. The image below shows the experiment immediately after adding the blocks.
Container 1
100 ml water at 25°C
10 cm iron at 40°C
Container 2
100 mL water at 25°C
10 cm lead at 40°C
Why did the temperature increase more for container 1 even though each 10 cm block was heated to 40°C and placed in 100 mL of water at 25°C? A. Different materials can have different densities.
В. Different rates of dissolving. C different materials have different capabilities of transferring heat. D. Different materials can have different rates of sinking.
